There's nothing made up about "No sparks, no power" I wouldn't

What kind of sparks does a Diesel need?

This ine has a FADEC. No electricity and you have a big weight up
front.

Worse, in the twin star installation, both engines are tied to an
electrical system that can punch out both at the same time. in this
case, when the gear was retracted...

Nice eh?

To be fair, there was an immediate AD requiring a backup battery
systtem to power the FADECs after that event. *I'm surprised it
wasn't

required for certification in the first place since it appears to
me that it was a forseeable failure mode, but still.

There's lots of ways you can lose all electrics. Corrosion,
lightning, poor maintenance...

I agree. Isn't that a problem for electrical ignition systems?


Well, there are two mostly! Completely independent as well. Not the case
here. You can add backup batteries and what not, but they're still
connected to the same fadec.

Limp
home should be excellent in a diesel...

Should be, but in this engine it is non-existent. It's not diesels in
general I'm knocking. It's this engine only..
